Abstract
Description
Technical Field
[0001] This invention relates to the field of regenerative thermal oxidizer technology, and particularly to a regenerative thermal oxidizer and process with controllable temperature uniformity. Background Technology
[0002] Regenerative Thermal Oxidizers (RTOs) are highly efficient organic waste gas treatment devices. Their working principle involves using high temperatures to oxidize and decompose organic waste gas into harmless carbon dioxide and water, while simultaneously recovering heat through a heat storage medium to reduce energy consumption. However, in actual operation, uneven temperature distribution within the RTO is a significant problem. This not only affects the treatment efficiency of organic waste gas, leading to incomplete combustion of some waste gas, but also shortens the equipment's lifespan and increases operating costs. Therefore, developing an operating process for RTOs that can effectively control temperature uniformity is of great practical significance. Meanwhile, biomass combustion boilers and equipment, including furnace baking, melting, and electric furnace manufacturing technologies, occupy an important position in energy utilization and industrial production.
[0003] In order to improve temperature uniformity, existing technologies typically employ methods such as optimizing burner arrangement and adjusting air volume, but the results are not ideal.

[0038] This invention discloses a process for a regenerative incinerator with controllable temperature uniformity, comprising the following steps: 1. Preliminary preparation stage: Conduct a comprehensive inspection of the regenerative thermal incinerator, preset the initial operating parameters according to the parameters of the waste gas to be treated, including the target value of combustion temperature, air volume, and switching cycle of the regenerator 19. The target value of combustion temperature is set between 750-850℃. Start the preheating system to preheat the regenerator 19, and monitor the temperature of the regenerator 19 in real time to ensure uniform preheating. 2. Waste Gas Treatment Stage: The waste gas to be treated is introduced into the incinerator body 1, and the electric burner 6 is started for heating and combustion. Multiple temperature sensors 5 collect the furnace temperature data in real time and transmit it to the control center. The temperature sensors 5 are distributed in different areas of the incinerator body 1. The control center controls the temperature deviation of each area in the furnace to within ±5℃. The control center controls the auxiliary burner 7 and the cold air valve to adjust the temperature according to the temperature deviation, and at the same time adjusts the waste gas flow rate and velocity. When the temperature of a certain area is lower than the preset value, the control center controls the corresponding auxiliary burner 7 to start or increase its combustion power; when the temperature of a certain area is higher than the preset value, the control center controls the corresponding cold air valve to open. 3.

If the temperature of the heat storage body 19 that does not meet the standard is heated or cooled, before switching, if the temperature of the heat storage body 19 that is about to be put into use is lower than the preset combustion temperature target value, it is heated to the target temperature by an auxiliary heating device; if the temperature of the heat storage body 19 that is about to be taken out of use is too high, it is cooled by a cooling device. 4. Post-treatment stage: The purified gas is discharged after heat recovery by the heat storage body 19. The heat storage body 19 is cleaned and maintained regularly, with a cleaning cycle of 1-3 months.
[0039] Example 3: Organic waste gas generated by a chemical enterprise mainly consists of toluene and xylene, with a concentration of 2000-3000 mg / m³ and a flow rate of 5000 m³ / h. It is treated using the regenerative thermal oxidizer operation process with controllable temperature uniformity of this invention. The specific steps are as follows: Preliminary preparation stage • After checking all components of the incinerator and confirming that they are normal, the preset target combustion temperature is 800℃, the heat storage switching cycle is 1 hour, and the air volume is set to 6000m³ / h according to the exhaust gas flow and combustion requirements.
[0040] • Start the preheating system to preheat the heat storage body. The temperature of the heat storage body gradually rises to 780-820℃ through temperature sensor monitoring, and the preheating is uniform.
[0041] Waste gas treatment stage • The exhaust gas is introduced into the incinerator, and the burner is started to heat it to 800°C. Temperature data is collected in real time by six temperature sensors distributed in the upper, middle, and lower zones of the furnace.
[0042] • Data analysis by the control system revealed that the temperature in the lower region of the furnace was 790℃, 10℃ lower than the preset value. Therefore, the two auxiliary burners corresponding to this region were activated, and the combustion power was adjusted to 60% of the rated power. Simultaneously, the temperature in the upper region was found to be 810℃, 10℃ higher than the preset value. Therefore, the corresponding cold air valve in this region was activated, with a cold air flow rate of 50 m³ / h. After adjustment, the temperature in all regions stabilized between 795-805℃.
[0043] • Based on the temperature distribution, appropriately increase the exhaust gas flow rate near the lower region to 5500 m³ / h, and adjust the exhaust gas flow rate near the upper region to 4500 m³ / h to further maintain temperature uniformity.
[0044] Heat storage switching stage • When the switching cycle is reached, the temperature of the heat storage medium to be put into use is detected to be 770℃, and it is heated to 790℃ by an auxiliary heating device; the temperature of the heat storage medium to be taken out of use is 830℃, and it is cooled to 810℃ by a cooling device.
[0045] • Precise control of valve switching, with furnace temperature fluctuations within ±3℃ during switching, and the temperature quickly recovering to around 800℃ after switching is completed.
[0046] Post-processing stage • After the purified gas recovers heat through the heat storage medium, the exhaust temperature is 150℃, which meets the emission standards.
[0047] • Clean the heat storage medium once a month to ensure its heat exchange efficiency.
[0048] After a month of operation, the incinerator achieved an efficiency of over 99% in treating organic waste gas, and the equipment operated stably without any malfunctions caused by uneven temperature.
[0049] The specific usage and function of this embodiment: In this invention, on the control center interface, temperature sensor 5 is activated to monitor the internal temperature of the incinerator body 1 in real time and transmit the data to the control center. Electric burner 6 is activated, and the control center adjusts the heating power of electric burner 6 according to a preset program, working in conjunction with auxiliary burner 7 to preheat the inside of incinerator body 1. Temperature sensor 5 continuously monitors the furnace temperature, and the control center automatically adjusts the gas supply of auxiliary burner 7 and the heating power of electric burner 6 according to the set incineration temperature range, so that the furnace temperature gradually rises and stabilizes within the preset range. When the temperature approaches the preset incineration temperature, the intermittent adjustment motor 13 is started on the control center. The intermittent adjustment motor 13 drives the dispersion frame 14 to start rotating slowly. External exhaust gas enters the temporary storage tank 9 of the diversion frame 8 through the air supply pipe 10. As the dispersion frame 14 rotates, when the air inlet 15 connects with the temporary storage tank 9, the exhaust gas, under the action of pressure difference, enters the corresponding heat storage body 19's air passage space through the air inlet 15. When the exhaust gas flows through the heat storage body 19's air passage space, it exchanges heat with the heat storage body 19, absorbing the heat stored in the heat storage body 19, thus achieving preheating. The temperature of the preheated exhaust gas increases, which is more conducive to subsequent incineration in the incinerator body 1. After preheating, the exhaust gas enters the combustion space of the incinerator 1 from the exhaust space of the heat storage body 19. Under the combined action of the high temperature generated by the electric burner 6 and the flame of the auxiliary burner 7, the harmful substances in the exhaust gas react fully with oxygen and undergo combustion decomposition, transforming into harmless or less harmful substances such as carbon dioxide and water. The purified gas after combustion is at a relatively high temperature and enters the exhaust space of the heat storage body 19 on the other side. During this process, the purified gas transfers its own heat to the heat storage body 19, causing the heat storage body 19 to heat up and store heat. At the same time, the temperature of the purified gas itself decreases. Subsequently, the cooled purified gas passes through the exhaust port 16. The heat is fed into the central tank 11 and finally transported to the external recycling equipment via the external discharge pipe 12. The monitor 24 detects the temperature of the heat storage body 19 in real time and transmits the data to the control center. When the temperature of the heat storage body 19 is lower than the preset value, the control center activates the heating ring 25, and the heating components inside it work. The heat is transferred to the heat storage body 19 through the docking plate 27, causing its temperature to rise. When the temperature of the heat storage body 19 is higher than the preset value, the control center activates the cooling ring 26, and the cooling components inside it work. The heat storage body 19 is cooled down through the docking plate 27, ensuring that the heat storage body 19 is always in a good heat exchange working state.

9. An operating process for a regenerative incinerator with controllable temperature uniformity, characterized in that: Includes the following steps: (1) Preliminary preparation stage: Conduct a comprehensive inspection of the regenerative incinerator, and preset the initial operating parameters according to the parameters of the waste gas to be treated. The initial operating parameters include the target value of combustion temperature, air volume, and the switching cycle of the heat storage body (19). The target value of combustion temperature is set between 750-850℃. Start the preheating system to preheat the heat storage body (19) and monitor the temperature of the heat storage body (19) in real time to ensure uniform preheating. (2) Waste gas treatment stage: The waste gas to be treated is introduced into the incinerator body (1), and the electric burner (6) is started to heat and burn. The temperature data inside the furnace is collected in real time by multiple temperature sensors (5) and transmitted to the control center. The temperature sensors (5) are distributed in different areas of the incinerator body (1). The control center controls the temperature deviation of each area inside the furnace to within ±5℃. The control center controls the auxiliary burner (7) and the cold air valve to adjust the temperature according to the temperature deviation. At the same time, the waste gas flow rate and velocity are adjusted. When the temperature of a certain area is lower than the preset value, the control center controls the auxiliary burner (7) corresponding to that area to open or increase its combustion power. When the temperature of a certain area is higher than the preset value, the control center controls the cold air valve corresponding to that area to open. (3) Heat storage body (19) switching stage: The heat storage body (19) is switched according to the preset switching cycle. Before switching, the temperature of the heat storage body (19) is detected.
